Problem Stapling Vinyl to Plywood

I bought a Pasolde 100 Upholstery stapler to attach vinyl to plywood
frames. When we shoot the staples they just about go through the vinyl
and any stretching causes the vinyl to pull through. The vinyl supplier
said it is marine grade (aka good) material.
There is no depth adjustment (or safety) on this model. The manual
says to use between 80 and 100 psi. Even with the pressure turned down
to 40psi, the minimum required to operate the unit, the problem
persists.
Is there a technique we should be using or other tricks required for
vinyl? Could it be a defective gun? Does someone have a different model
that works with vinyl? We reverted to the hand stapler for that project
but need something better for the next. Thanks, JG

Check how far the striker tongue protrudes from the nozzle when fired.
You can always file it down a bit and try again until you get it right.
As you are considering replacing the unit, It's a nothing tried nothing
gained situation :)

You should be able to control the penetration by either a mechanical
adjustment or controlling the air pressure.
Turning the edge of the vinyl under and stapling through a double
thickness may help but should not be required.

Have a look at this site:
http://www.itwconstruction.ca/cgi-bin/showproduct.asp?prodcode=US-100&paslode=1
it gives a link to the product manual for stapler US-100.
Page 13 )I think) says if fasteners penetrate too deeply adjust the
contract piece.

Thanks.. I loosened the screws and found, however, no room for movement. Looks
like it's a job for the supplier. Cheers, JG
